摘要：Dryland in West Nusa Tenggara (NTB) is generally a marginal land with soil fertility, water availability, and low organic C levels so that productivity is low. This study analyzed changes in soil properties on dry land due to soil destruction and different doses of inorganic fertilizers, as well as their effect on the growth and yield of onion plants. The experiment was conducted from September to November 2020 in Labuhan Lombok Village, Pringgabaya Subdistrict, East Lombok Regency, on land with inceptisol soil type and a place height of 22.3 m above sea level. The experiment was designed based on a factorary Randomized Design Group (RAK) of two factors, namely soil destruction and inorganic fertilizer dosage. The first factor of soil destruction consists of 4 levels of treatment, namely without soil destruction (P0), manure 20 tons/ha (P1), biochar 5 tons/ha (P2), and waste backlog mushrooms 10 tons/ha (P3) while inorganic fertilizer dose consists of 3 levels, namely NPK 150 kg/ha (N1), NPK 300 kg/ha (N2) and NPK 450 kg/ha (N3), produced 12 combinations of treatments repeated 3 times so that the experiment was conducted on 36 plots. The results showed that there was an interaction between soil destruction and inorganic fertilizer doses to C-organic (P3N1) and soil KTK (P1N2). The provision of soil destruction affects the nature of the soil, namely pH, N-Total, K-Total, and soil type weight while the dose of inorganic fertilizer has no real effect on the chemical and physical properties of the soil. The provision of soil waste backlog mushrooms 10 tons/ha can increase the content of C-organic soil by 1.33%. There is no interaction between the administration of soil and the dose of inorganic fertilizers to the growth and yield of onion plants. Soil destruction affects the height of plants aged 42 hst and the number of leaves aged 49 and 56 hst while the dose of inorganic fertilizer affects the height of the plant aged 49 hst and the number of leaves at the age of 49 and 56 hst as well as the results of onion plants. The dose of inorganic fertilizer NPK 450 kg/ha affects the yield of onion plants, which is 1.67 kg/plot.
